Schreiner has produced (in my opinion) a fantastic volume dealing with the message of Romans. Much in the work is to be appreciated:
1) He provides an overarching view of each passage, summarizing it as a whole before breaking it down. This allows us to see the big picture as well as the pieces that make it up.
2) He approaches the text from a conservative standpoint, assuming that Paul intended to write a consistent message. In doing so, he shows that one doesn't need to bend over backwards to see a coherency in Paul's thought.
3) He interacts with an overwhelming number of scholarly commentaries on Romans, never afraid to explain opposing views and interact with them.
Thomas Schriener's Romans commentary is the best I have ever used.This commentary is both readable and scholarly. It is great for preaching, exegetical study, scholarly use, and bible study. I highly reccommendit to pastors and seminary students.
